Can a PDF file be password secured automatically on a per user basis.

I want to sell my content in PDF files. After an online payment is recieved, I would like a unique password keyed to the individual transaction to be stored in the PDF which the end user would then be allowed to download.

This would in effect serialize the content to the user who purchased it. That way if the file got shared I could track it back the person responsible, and without the specific code no individual file would be usable.
